Bar checks
..........
Though not strictly necessary, _bar checks_ should be used in the input
code to show where bar lines are expected to fall. They are entered
using the bar symbol, ‘|’. With bar checks, the program can verify that
you’ve entered durations that make each measure add up to the correct
length. Bar checks also make your input code easier to read, since they
help to keep things organized.
